BUILDING STRUCTURE.

Specification of Letters Patent.

Patented Nov. 11, 1919.

Application filed January '30, 1919. Serial No. 274,051.

To all whom it may concern:

Be it known that I, JOHN JAY FoX, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Building Structures, of which the following is a specification.

This invention relates generally to building structures, and particularly to cold storage buildings and warehouses.

In the construction of cold storage buildings and warehouses it is of prime importance that all of the walls be insured against heat losses, in order that the temperature within the building and rooms thereof may be maintained at a constant predetermined degree. In accomplishing this end a number of different methods of constructing the walls of the building have been proposed, but such proposed methods have their disadvantages. In one instance it is suggested that plates or thicknesses of heat insulating material be positioned upon the inner face of the curtain wall from floor to floor, but no means has been proposed in such method to insulate the spaces between the floors and between the edges of the heat insulating plates. It is evident, therefore, that such method has not met with entire success, as a perfect or complete heat insulation of the outside wall is not possible. Again, it has been proposed to build the curtain wall separate from the building structure or framework, and to interpose between this wall and framework a continuous and unbroken heat insulating surface. While such a method may be successful from the standpoint of heat insulating the walls, the eX- pense incident to the erection of the curtain wall independent of the building structure or framework has proved a serious drawback.

It is the primary object of my invention to provide a building structure having the curtain wall thereof spaced from the building framework and yet supported by the latter, thus avoiding the expense incident to the erection of a curtain wall independent of the framework and providing means whereby a continuous and unbroken plate of heat insulating material may be effectively supported upon the inner face of the curtain wall not only from floor to floor but from the bottom to the top of the building and from end to end.

This object is accomplished by arranging upon the building structure or framework novel supporting means for the curtain wall, whereby the latter is supported by the building framework and is a part thereof and yet is spaced beyond the framework a distance suflicient to permit of the application of the heat insulating plate or plates between the building structure and the curtain wall.

In the accompanying drawing I have illustrated the preferred means for the accomplishment of the object set forth, but it is obvious that variations may more or less be made in the construction herein illustrated without departing from the spirit of the invention.

In the drawing,

Figure 1 is a fragmentary horizontal sectional view taken through a part of a building structure constructed in accordance with the invention, the view being taken substantially upon line l-l of Fig. 2,

Fig. -2. is a fragmentary front elevation of the building and illustrating parts broken away to show the formation of the building framework, the supporting means for the curtain wall, and the heat insulating plate, and

Fig. 3 is a vertical sectional view taken substantially upon line 3-3 of Fig. 2.

Referring now more particularly to the drawings, 10 indicates the upright girders of the building framework, and 8 indicates the cross beams connecting the upright girders and supporting the floors of the building; The construction of these girders and their formation and arrangement may be difierent from that disclosed in the drawing.

The curtain or outside wall of the build ing may be formed of brick or any other suitable material, and is indicated at 6. This Wall is built up slightly beyond the outer face of the supporting framework so as to provide a space between the framework and the wall, and the said wall is supported at the various floors by the horizontally disposed girders or beams 4. These beams or girders rest upon brackets 5 projecting outwardly from the building fran'iework, as shown particularly in Fig. 8. The brackets 5 may be formed integrally upon either the upright girders 10 or the horizontally disposed girders 8, or they may be constructed independent of the framework and bolted thereto as desired.

The length of these brackets will depend upon the width of the space it is desired'to produce between the curtain wall 6' and the outer faces of the building framework,

and the brackets if built insubstantially the proportions illustrated will prove 'sufliciently strong to withstand the weight or pressure to which they will be subjected.

The insulating material is indicated at 7,

and may be formed ofcork, composition or anyiother suitable material. It may be preferred to construct this insulating material in' plates of relatively small dimension so thatthey may be easily and conveniently handled, and the various plates areinserted in the space betweenthe curtain wall and the building framework and secured therein in any desired manner, It will be understood tlntthe various plates of insulating maandthe building framework but the plates may be cut out at their edges so as to accommodate themselves to the brackets wherever encountered. By reason of the fact that the brackets are relatively small and are spaced apart a relatively great'olistance, the lack of insulating material at these particular points will be of no consequence sofar as concerns the proper insulation of the wall. It will be understood that the plates of insulating material will be tightly fitted around the various brackets so as to properly seal the wall against the passage of heat units.

By constructing a cold storage building or warehouse in the manner described it is obvious that the walls are effectively closed to the passage of heat and cold. The curtain wall is firmly held and supported by the building framework without the necessity of resorting to the expensive and cunt bersome exterior columns and girders which it has been heretofore proposed to use. The brackets 5 which support the cross beams or girders 4 will also assist in supporting the insulating plates 7 Having thus fully described my invention, I claim In a building structure, the combination of a framework including upright girders and cross-beams connecting the upright girders and supporting the floors of the building, a curtain wall erected independently of and spaced from the framework, brackets projecting horizontally from the upright girders at the juncture of said girders with the cross-beams and substantially in horizontal alinement with the floors, horizontal girders embedded in the inner face of the curtain wall. and supported upon the outer portions of said brackets, and a lining of insulating material upon the inner face of the curtain wall in the space between said wall and the framework. said lining covering the inner portions of the brackets and inner faces of the horizon.- tal girders.

In testimony whereof I afiiX my signature,

JOHN J AY FOX.
